AussiePilot:
I would suggest you consider using KL-100 instead of the KL-200. The KL-100 has 20% Klotz Benol racing castor in it. I run 18% total oil, of which 14.4% is synthetic and 3.6% is castor. I personally run 15% nitro, which I have readily available here in the states in 5-gallon pails and 30-gallon barrels. I DO run this fuel in my 4-strokes. I recommend 2% castor in these 4-stroke engines, and no more than 4% to keep from gumming it up a bit. For your 2-strokes, you can use this fuel at 5% nitro fine, and NOT have to add another Cruel Power fuel to it for the castor content. IF you like, you can add 5 ounces of AA castor in the summer there for additional protection in the higher heat (2-strokes only) Also, Benol castor has a higher film strength than regular AA castor, and therefore, will stay on the crank for better lube on the bottom end. I am a Klotz dealer and have been mixing my own fuel since I was 12 years old and in competitive rat racing and combat control line. . You are using the original Techniplate, and the oil with the Benol in it is about the same price, so use the on with the Benol racing castor in it. It is 20% by volume Benol racing castor and 80% original Techniplate.
